below is the script field

```auto
GET log-2022.03.30/_search
{
  "script_fields": {
    "message": {
      "script": {
        "lang" : "painless",
        "source": "doc['message.keyword'].value"
      }
    }
  }
}

```

and here is the result I got

```auto
"failures" : [
      {
        "shard" : 0,
        "index" : "log-2022.03.30",
        "node" : "Jei35aKrR0-jxyKKld12jss",
        "reason" : {

            "org.elasticsearch.index.fielddata.ScriptDocValues$Strings.getValue(ScriptDocValues.java:508)",
            "doc['message.keyword'].value",
            " ^---- HERE"
          ],
          "script" : "doc['message.keyword'].value",
          "lang" : "painless",
          "position" : {
            "offset" : 22,
            "start" : 0,
            "end" : 28
          },
          "caused_by" : {
            "type" : "illegal_state_exception",
            "reason" : "A document doesn't have a value for a field! Use doc[<field>].size()==0 to check if a document is missing a field!"
          }
        }
      }
    ]

```

Kindly help on this.

Hey,

why is it not possible, that any of your documents does **not** have the message field set? Can you verify that using an exists query for that field, no documents are returned? Can you provide a fully reproducible example, that contains a sample document containing a message field and that error message, so we can reproduce locally?

Hi Spinscale ,  
every document have the message field with some data present to it.  
I have verified it with query and got the data. but the only issue is when I try to read data with 'message.keyword' it gives no data. Below is the query :-

```auto
GET logstash-index-xxx/_search
{
  "size": 0, 
  "aggs": {
    "message": {
      "terms": {
        "script": {
          "source": "doc['message.keyword'].value"
        }
      }
    }
  }
}

```

As of now I have resolved the issue with enabling **'fielddata=true'** but now the issue is when I try to see the logs for 7 days or more, It takes longer time and eventually fails giving internal server error ("failed to execute")
